H AT nETA NIN AND DISTRIBUTING ELEMENT.

Application filed Janee -1927. Serial No. 160,922,.

This invention relates to an improved. appliance or element designed for the purposes of heat retentlon and distribution of heated gases in furnaces, boilers, or other heating fixtures in which an open oil or gas flame is employed.

Briefly, the

invention has particular reference to a body of appropriate shape and material which is to be placed over the burner in a combustion chamber and which serves as a device for the 'absorptiomretention, and dissemination of heat, from the ignited gases. i

The present invention is not: tov be confused with inventions similar in appearance, which constitute a part of a burner structure, and which are employed as'mixers and fuel distributors to aid in combustion. Instead, it is a separate'and independent body supported above the burner by appropriate means, for retention, distribution and dissemination of heat from the ignited gases when produced by a flame from any suitable source of fuel.

The chief feature of my invention is the provision of a refractory block containing layers or rows of bores, each layer of bores being atright angles to the layer above and the layer below. Because of this heat passes up through intersecting holes to the difier-ent layers of bores and also through the bores in diiferent directions to sides of the fire chamber and produces an even heat distribution. The heat retaining and distributing element being characterized by the various layers of bores heats quickly and holds the heat.

The preferred embodiment of the invention as well as the structural features embodied therein, will become apparent from the followingdetailed description and drawings. A

In the drawings Figure 1 is a side view of a device constructed in accordance with the present invention, showing the manner in which it is adapted'to be supported above a burner.

Fig. 2 is a central cross section taken approximately upon the plane of the line 2-2 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a top plan view of the block with a portion broken away and in section. 7

Referring now to the drawings in detail, it will be seen that the reference character 1 designates generally a burner of any suitable construction above which the invention g nerallyv designated by the reference character is supported in any appropriate .inanner. stantially circular body of fire clay of relatively. largepropo'r-tion with respect to the fires of theburner. This body is of a diaineter, however, to permit its peripheral portion to be disposed in spaced relation tothe surroundingwall ofthefire box in which'it- .isadapted to be suspended.

r he body is formed in its flat topand bottom 'faces'with substantially semi-circulargrooves. The respective sets of grooves are disposed in parallelism with each other and extend in the same direction, for in stance, 11011'1 left to right in F 15:. l. The

grooves in the. top'of the block are designated by the reference characters 3; while the grooves in the bottom are designated by the reference characters 4:.

Two different groups of bores are formed in the block or body. For instance, one group These are shown for instance in Fig. 1. .The bores of the top row are designated at 5, those of the central row at 6, and those in the bottom row at 7. It will be noticed that the bores in each layer are in the same hori Zontal plane but are so arranged as to dispose them in staggered relation with respect to the bores of the other layer. The sectional view in Fig. 2, which is taken to show these bores at right angles to the disposition O0,

in Fig. 1, also brings out the fact that the top layer of bores intersects the bottom portions of the grooves 3, in such a manner as to provide openings affording communication between these top grooves 3 and the top bores 5 as shown better in Fig. 3.

The bores 7 of the lowermost row, which are also the largest in diameter, intersect the bottom grooves 4. Thus far, we-have a circular body having parallel grooves in 1 its flat top and bottom together with right angularly disposed bores intersecting these grooves.

' The second group of bores is composed of two horizontal rows, the bores of the top the aforesaid bores 7 and 6. These bores 9 H0 The invention comprises a vsub- 60 comprises three layers of bores. 80

V with the extend at right angles to the bores 6 and 7, and intersect and communicate with the last named bores. The bores 8 extend at right angles to and intersect and communicate with the bores 5 and 6. From the foregoing description, it will be seen that I have evolved and produced an exceptionally simple and inexpensive heat retainer and distributor in the form of a circular block of fire clay, having flat top and bottom surfaces provided with spaced parallel grooves.- The portion of the body between these grooves is formed with two groups of horizontal rows of bores, there being three rows in one group and two rows in the other group, making a total of five. The bores of the first group extend at rightangles to the grooves and also at right angles to the bores of the second grou It is believed t at the construction, as well as the features and advantages and operation of the invention will be clear when considering the description in connection drawings. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it

is to be understood, that changes in the shape, size and proportions may be resorted to without departing from the spirit of the adjoined claim.

Having thus described my invention, what through opposite sides of. the body and dis 7 posed at right angles to said grooves, the

bores of the two outer rows intersecting and communicating with the adjacent grooves, and the second group of bores comprising two vertically spaced horizontal layers of boxes extending in the same direction as said grooves, and at right angles to the bores of said first group, the bores of saidsecond group intersecting and being in communication with the top and bottom rows-of bores in said first group and also intersecting and being in communication with the intermediate row of bores in the first group.

In testimony whereof l affix my signature.
